Common Problems:
Audio Drop Outs - at least 3X per day
Picture Freeze - need to change the channel to release
Picture Breakup - just wait - it fixes itself
Picture Lag - seems to show in slow-mo every few seconds - change channel and go back - no more lag.
HD - SD -HD - broadcast starts on 16x9 HD - then goes to 4x3 with side bars then back to HD - Issue at HD provider - not cable carrier.
I watch nothing but HD on my system. Personally I believe much of this has to do with compression as cable trys to add channels. I have 2 6412's (III) and they both do the same thing...at the same time.
Still love HDTV but I never thought there would be so many problems with it. . . it has been over 6 years since it came out.

Setup:
I have a Comcast Motorola DCX3400 and a the new 37" Vizio SV370XVT, connection type HDMI.
Symptoms:
The symptoms was the sound dropped when I changed between Hi Def channels.
When I switched to a Low Def and changed between Low Def channels the sound came back. When I changed back to Hi Def the sound was still missing. A quick fix was to turn either the TV or the cable box off\on. I exchanged with same model LCD TV, same symptoms.
Fix:
I called Comcast and managed to fix the problem by changing the cable box HDMI audio settings from auto to L-PCM.
Instructions how to fix:
To access the motorola settings turn on the cable box and TV. Press and hold down the power button first then menu, wait until the box turns off and the message indicator comes on(a small picture of an envelope bottom right corner of display). Release power button first quickly followed by the menu button. The cable box now displays 16:9. use the arrows to move cursor. Press down button to Additional HDMI settings and press right button to access the submenu. Goto to Audio Output and with right arrow change from Audio to L-PCM. This change resolved my problem with the the audio drops in Hi Def channels.
